Expected behavior

As a developer I want to be able to use the azure-functions plugin in a multi module project.
Either fix or provide guidance on how to do this correctly.

Actual behavior

Packaging is probably not correct.

Steps to reproduce the problem

Sample project

Build and run with:

mvn --projects azfunctions-multimodulefunction --also-make-dependents clean package azure-functions:package azure-functions:run

It will run but when triggering the function from a browser with http://localhost:7071/api/hello?name=hans it will fail with a reflection error.
Probably because packaging does not work correctly now.

Workaround:

1. Remove the functions project from the multi module project
2. Make the functions project a stand alone project that refers the artifacts from the multi module project.
3. Do a mvn clean package install on the multi module project.
4. Do a mvn clean package azure-functions:package azure-functions:run on the function project

This workaround requires extra steps on the build environment instead of a one liner in Maven.

Hi @nicenemo , the Sample project link does not exist any more. Would you mind to give it again so I can see what's happenning? 😄

[nicenemo]

Sorry but we simplified our code "ages" ago so we do not need it for now.
That's why I deleted the old sample projects. Maybe I will try again after we moved to the latest version of the stack that does not require shading.

Hi @nicenemo, thank you for your feedback.

Just sorry to say that I'm going to close this issue for now since it is inactive for a while. But feel free to reopen it if you find this is still a problem.

Thank you for your contribution!
